The problem asks to determine which number corresponds to point B on the coordinate line.

Point B is located at the position 2 on the number line. The four answer choices are square roots of numbers:

A) $\sqrt{2}$
B) $\sqrt{3}$
C) $\sqrt{5}$
D) $\sqrt{6}$

We need to check which of these values is closest to 2. Here are the approximate values of the square roots:

• $\sqrt{2} \approx 1.41$
• $\sqrt{3} \approx 1.73$
• $\sqrt{5} \approx 2.24$
• $\sqrt{6} \approx 2.45$

Among these, the closest value to 2 is $\sqrt{4}$, but that is not in the answer choices. However, the closest approximation from the provided options is $\sqrt{5}$, which is approximately 2.24.

Thus, the correct answer is C) $\sqrt{5}$.

Do you need more details or have any questions?

Here are five related questions to think about:

1. How can we estimate square roots without a calculator?
2. What is the value of $\sqrt{4}$ and why is it relevant here?
3. How would the answer change if point B were located at 3 on the number line?
4. Can you think of other ways to visually represent irrational numbers like $\sqrt{5}$?
5. How do the square roots of non-perfect squares behave on a number line compared to perfect squares?

Tip: When estimating square roots, you can always look for perfect squares near the number you are approximating to get a rough idea.
